For a veteran, XinBingLian is the happiest, and the first year after joining the company is the most painful. Recruits do it, veterans watch it, and stand back after more than three years. This is the actual situation of the army. The first year is enough to make you slim down.
3: 2-3 cm in length and height is no problem. Veterans will let you go. You have to train by yourself. Your constitution is your own. Crying is normal. Many people can't stand crying. I will understand later! If you are a man, you should dare to do it. Be decisive. What's the use of asking for advice in 7788! Make your own decisions!
Personal military experience, I hope to help you a little!
